Hexadecimal

Hexadecimal is a base-16 numbering system used in computing and digital electronics. Unlike the decimal system, which uses ten digits (0-9), hexadecimal includes six additional symbols: A, B, C, D, E, and F, representing values 10 to 15. This system is compact and efficient, allowing for the representation of large binary numbers in fewer digits, making it easier for programmers and engineers to read and write. For example, the decimal number 255 is represented as FF in hexadecimal. It is commonly used in areas like color coding in web design and memory addressing in computers.
